degrees

deg. lies in the quadrant

little more:

It is the as , but a reference angle.

But in the second quadrant is and is

so,
}

This will summarizes all:
Quadrant I: 0 to 90 degrees = 0 to p/2 radians
Quadrant II: 90 to 180 degrees = p/2 to p radians
Quadrant III: 180 to 270 degrees = p to 3p/2 radians
Quadrant IV: 270 to 360 degrees = 3p/2 to 2p radians
where p = 3.14 rounded to 2 decimal places.
